Abstract

A new approach to experimental studies in the water column of lakes and reservoirs using the Vinci robotic profilograph is presented. The autonomous underwater vehicle is designed to conduct regular multiparameter measurements of vertical profiles (to a depth of 60 m) over a long period of time (>1 month) in automatic mode at a moored hydrological station. Experimental operation of the device was carried out in Lake Glubokoe (Ruza district, Moscow region) in 2022–2023. The observations made it possible to describe in detail the seasonal evolution of the aquatic environment, including the transition from a state of homothermy to direct thermal stratification of the lake with the formation of hypoxia in the hypolimnion in the central deep-water basin of the lake. Intense diurnal fluctuations in the concentration of dissolved oxygen and water temperature and turbidity were found in the bottom layer. A hypothesis has been put forward that in the spring–summer period, hypoxia is formed not only due to the barrier effect of the metalimnion, but also due to the increase in oxygen consumption for the microbiological oxidation of detritus particles raised from the bottom by pulsating groundwater springs and stirred up in the bottom layer.
